To a/ZZ whom it may concern,.-

Be it known that I, GOD'FREY J. KAPLAN, a citizen of the United States, residing at Owatonna, in the county of Steele and State of Minnesota, have invented certain new and useful Improvements in a Combined Ohurn and Butter-Vorker; and I do hereby declare the following to be a.full,clear, and exact description of the invention, such as will enable others skilled in the .art to which it appertains to make and use the same.

My invention has for its object to provide an improved machine adapted for use as a butter-worker or as a combined churn and butter-worker; and to this end it consists of the novel devices and combinations of devices hereinafter described, and dened in the claims.

In the `accompanying drawings, which illustrate the invention, ike characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a view in side elevation, showing the improved machine. Fig. 2 shows the drum or body of the churn in end elevation, but with certain other parts sectioned on the line :n2 x2 of Fig. 1, and Fig. 3 is a transverse vertical section taken on the line x3 of Fig. 1. Fig. 4 is a view corresponding to Fig. 3, but illustrating a slightly-modified form.

In this improved machine a horizontallydisposed drum 1 of any suitable construction, but preferably having peripheral doors 2,v is employed. Heavy gudgeons 3 and 4 project axially outward from the opposite heads of the drum, and these are j ournaled in suitable bearings of a lpair of bearing-brackets 5 6, which brackets, as shown, are tied together by rods 7.

Within the drum is a plurality of deeplycorrugated rollers 8, that extend parallel to the axis of the drum and vare spaced equidistant from the said drum-axis and are spaced equidistant apart. Secured to the inner surface of the drum radially outward from each roller 8 is a lifting shelf or flight 9, that extends, preferably, from end to end of the drum. Each roller 8 cooperates with one ofthe shelves-to wit, the adjacent shelf 9; but some little space should be left between the most nearly approaching portions of the said coperating rollers and shelves.

Means is provided for rotating the drum in direction of the arrow marked adjacent thereto on Fig. 3 the said rollers 8 should be rotated in the direction of the arrows marked Aadjacent thereto `in the same view, .Simple` and efficient means for imparting the abovenoted movements to the said drum and rollers is illustrated in the drawings and, as shown, comprises as follows: A large internal ringgear 10 is secured to one head of the drumto wit, to the right-hand head thereof-as shown in Fig. 1. The shafts or trunnions 8a of the rollers 8 project through thesame head of the drum and at their outer ends are provided with sprocket-wheels 11. Mounted in suitable bearings on their brackets 6l and on a shelf 6a thereof is a driving-shaft 12, which at its outer end carries a pulley 13 and at its inner end carries a spur-pinion 1,4, which latter meshes with the ring-gear 10. Said drivingshaft also carries a sprocket 15. The drumtrunnion 4 carries two sprockets 16 and 17,

i the former of which alines with the rollersprockets 11 and the `latter of .which alines with the driving-shaft sprocket 15. A sprocket-chain 18 runs over the sprockets 15 and 17. A sprocket-chain 19 runs over the roller-sprockets 11 and under the drumsprocket 16.

The use of the machine as a butter-worker will first be described.

Under the rotation of the drum in the direction of the arrow marked in Fig. 3 the cooperating rollers 8 and lifting-shelves 9 will be brought into action in succession on the mass of butter, which normally lies or tends to lie at the bottom of the drum, and will lift the same or cause the same to rise with the upwardly-moving part of the drum. While the butter is being lifted the roller 8, which is acting thereon, cuts off portions from the lower part of themass of butter and forces the same below the coperating liftingshelf 8. Most of the mass of butter will thus be cut up and worked through between the coperating roller and lifting-shelf before the butter is-carried to a point, high enough to cause it to roll inward over the top of the roller to the center of the drum; but any surplus of butter or butter which is not worked through between the roller and shelf will of IOO ' course be carried over to the center of the drum and again dropped to the bottom of the drum to be again commingled with the main body of the butter. By the above-described action the butter is not only worked in the sense that it is compressed and the water worked therefrom, but is cut up and then again commingled in such manner that there is a constant change and thorough commingling of all parts of the body of the butter. This manner of working the butter makes it possible to accomplishya substantial perfection in the distribution of salt throughout the body of the butter.

Hitherto, so far as I am aware, rollers which have been used to work butter have been caused to rotate on their own aXes in the same direction as that of the rotation of the drum. I believe it to be broadly new to rotate the working rollers in a direction reverse to that of the rotation of the drum and to provide means for cooperation therewith, whether fixed or movable, whereby the butter is cut or disintegrated and thereafter recommiingled. Hence I desire to clain this feature broadly.

The machine above described may be 'treated simply as a butter-worker or as a combined churn and butter-worker. In the butter-working action the machine may be run at quite a high rate of speed, partly because of the simplicity of construction, but more particularly because of the coperating action of' the rollers and lifting-shelves. Hence the machine may without change in its speed or readjustment of its i arts be used either as a churn or butter-wor ier. In lieu of the lifting-shelves 9 rollers 9a may be employed, as shown in Fig. 4. These rollers 9L if loose will in the butter-working action be frictionally driven in a direction reverse to that of the rotation of the coperating rollers 8. If positively driven, said rollers 9a sh uld be driven in a direction reverse to that of the Atation of the drum, su

rotation of the coperating rollers 8. In any event the rollers 8 and 9a would serve to cut portions from the bottom of a mass of butter being lifted thereby.

I claim as my inventionl. In a machine of the kind described, the combination with a rotary drum and a plurality of rollers therein eccentric to the axes thereof, said drum having internal means cooperating with said rollers to lift the butter and to cut portions from the bottom thereof, and driving means for rotating said drum in one direction and for rotating said rollers on their own axes in an opposite direction to that of the rotation of the drum, substantially as described.

2. In a machine of the kind described, the combination with a horizontally-disposed rotary drum and a plurality of corrugated rollers mounted therein eccentric to the axes thereof, said drum having internal liftingshelves outward of and coperating with the several rollers, and driving connections for rotating the drum in one direction and for rotating said rollers on their own axes in an opposite direction to that of the yrotation of the drum, substantially as described.

3. In a machine of the kind described, the combination with a horizontally-disposed rotary drum provided with three internal lifting-shelves 9, and three internal eccentric working rollers 8 each coperating with one of said lifting-shelves, and driving connections for rotating said drum in one direction and for rotating said rollers on their own axes in a direction op osite to that of the rolstantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
